SPECIFICATION forming part t Letters .Batent No. 790,464, dated May 23,1905.

Application filed Tanuary 21, 1905. Serial No. 242,117.

To a whom it may concern.-

scription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention relates to new and useful improvements in plows; and theobject of the invention is to produce a simple and efiicient device ofthis nature whereby the apparatus may be readily adjusted to accomplishthe various purposes referred to.

The invention is illustrated in the accompanying drawings, which, withthe letters of reference marked thereon, form a part of thisapplication, and in which Figure 1 is a perspective view of my improvedplow, showing the same adjusted for a subsoiler and grubber. Fig; 2 is asectional view on line 2 2 of Fig. 1. Fig. 3 is a detail View showing aturning-plow adjusted to the subsoiler. Fig. 4 is a detail view on line4 4 of Fig. 3.

Reference now being had to the details of the drawings by letter, Adesignates a plowbeam of the usual construction, having-handles B, whichare securely braced and bolted to the beam in the usual manner.

. C designates a subsoiling-plow having the lugs C at the upper endthereof, which are apertured to receive bolts D, and a portion E of theupright portion of said subsoiling-plow is bent at right angles and hasperforations E for the reception of bolts F, passed through i theplow-beam, as shown in Fig. 1 of the drawings. The lower portion of thesubsoilingplow is bent at right angles and has the angled cutting edgesH, and is adapted for use in loosening hard soil underneath the surfaceand also for grubbing.

Referring to Fig. 4 of the drawings, K des-' ignates a turning-plowhaving arms N, with apertures N therein, which are adapted to receivebolts N the upper of which bolts passes through an aperture N in theupright shank portion of the subsoiling-plow, the other of said armsbeing bolted to the lower angled portion of they plow. When theturning-plow is fastened to the'subsoiler, as shown in Fig. 3 of thedrawings, it will be observed that the lower edge of the turning-plowrests upon the upper surface of the subsoiler while the inclined edge ofthe turning-plow is in contact with one face of the upright portion ofthe subsoiler.

Referring to Fig. 1 of the drawings, I have shown a harrow attachmentcomprisinga bar O, having fingers O projecting therefrom. Said bar 0 ispivotally connected to the beam, and Q designates a rod which'ispivotally con nected to said bar at one end, and its other end ispivotally connected to one end of the angle-lever T, which is pivotallymounted upon the handles of the plow and provided for the purpose ofadjusting the angle at which it is desired to have said bar disposed.

From the foregoing it will be observed that by the provision of theapparatus shown and described I provide means whereby the subsoiling-plow may be converted into a turning-plow or pulverizing-plow bythe simple interchange of the parts shown.-

While I have shown a particular form of apparatus illustrating myinvention, it will be understood that I may vary the details of thesame, if desired, without in any way depart ing from' the spirit of theinvention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In combination with the plow-beam, a subsoiler having its upper portionbent at right angles and bolted to the under edge of a angled end of thesubsoiler, as shown and deploW-beam, lugs projecting from the subsoilerscribed. 10 and bolted tothe side of the beam, a turning- In testimonywhereof I hereunto afiix my plow having apertured arms projecting fromsignature in presence of two witnesses.
